Winding type electric reactor

Abstract

The invention discloses a winding type electric reactor in the technical field of electric reactors, which comprises an upper iron yoke, a lower iron yoke, a core column and a framework, wherein the framework is formed by connecting pulling plates; a coil is wound outside the core column on the framework; the coil comprises an inner-layer coil and an outer-layer coil; both sides of the outer-layercoil and the inner-layer coil form a triangle; and a triangular heat dissipation air passage is retained between the outer-layer coil and the inner-layer coil at both sides; When the winding type electric reactor is wound, a triangular support element is clamped between both sides of the outer-layer coil and the inner-layer coil; after winding is finished, the support element is drawn so that theheat dissipation air passage is in the triangle with stable structure; the heat dissipation air passage can not deform without an air passage support stripe between the outer-layer coil and the inner-layer coil; the triangular structure with same equivalent heat dissipating area has smaller side length than a rectangular structure and can save the coil; the winding type electric reactor has firmstructure, less coil usage and large heat dissipating area; and the invention can be used for a power grid and can improve the power running condition.

Description

technical field [0001] The invention relates to an electrical component, in particular to a reactor. Background technique [0002] In the prior art, there is a wire-wound reactor, which mainly includes a skeleton connected by an upper iron yoke, a lower iron yoke, a core column and a pull plate, and a coil is wound outside the core column on the skeleton, and the coil is formed from an inner After the inner layer coil is wound, airway stays are added to both sides of the inner layer coil, and the outer layer coil is continued to be wound outside the airway stays. In this way, the outer layer coil and the inner layer Two sides of the coil respectively form a rectangular heat dissipation air channel. Its disadvantages are: the reactor of this structure has a small area of ​​the heat dissipation air passage, which affects its heat dissipation effect, and the use of air passage stays increases the cost and wastes materials. Contents of the invention [0003] The object of th...
